Kusankha chobowolera choyenera cha pulojekiti yanu kumaphatikizapo kumvetsetsa zinthu zitatu zofunika: zinthu, zokutira, ndi mawonekedwe a geometric. Chilichonse mwa zinthuzi chimagwira ntchito yofunika kwambiri pakugwira ntchito ndi kulimba kwa chobowolera. Nayi njira yodziwira bwino momwe mungapangire chisankho chodziwikiratu.
Zinthu Zofunika
1. Chitsulo Chothamanga Kwambiri (HSS):
Chitsulo Chothamanga Kwambiri (HSS) chakhala chofunikira kwambiri pakugwiritsa ntchito zida zodulira kwa zaka zoposa zana, chifukwa cha kugwiritsidwa ntchito kwake kwakukulu komanso mtengo wake wotsika. Zidutswa za HSS zodulira zimadziwika chifukwa cha kusinthasintha kwawo, zimagwira ntchito bwino ndi zodulira ndi manja komanso nsanja zokhazikika monga makina odulira. Ubwino waukulu wa HSS ndi kuthekera kwake kokonzanso, kukulitsa moyo wa zodulira ndikupangitsa kuti zikhale zosankha zotsika mtengo pazida za lathe. Kuphatikiza apo, HSS ili ndi mitundu yosiyanasiyana, iliyonse yokhala ndi zinthu zosiyanasiyana kuti ikwaniritse zosowa zinazake zodulira. Kusiyanasiyana kwa mitundu yachitsulo kumeneku kumawonjezera kusinthasintha kwa HSS, zomwe zimapangitsa kuti ikhale yosinthasintha komanso yofunika kwambiri pantchito zosiyanasiyana zodulira.
2. Cobalt HSS (HSSE kapena HSSCO):
Poyerekeza ndi HSS yachikhalidwe, Cobalt HSS imawonetsa kuuma kwapamwamba komanso kupirira kutentha. Kuwonjezeka kumeneku kwa makhalidwe kumapangitsa kuti zinthu zisawonongeke kwambiri, zomwe zimapangitsa kuti zinthu zobowola za HSSE zikhale zolimba komanso zothandiza. Kuphatikizidwa kwa cobalt mu HSSE sikuti kumangowonjezera kukana kwake kukwiya komanso kumawonjezera moyo wake wonse. Mofanana ndi HSS yokhazikika, zinthu za HSSE zimasungabe ubwino wokhala ndi mano obwezerezedwanso, zomwe zimawonjezera moyo wawo wogwiritsidwa ntchito. Kupezeka kwa cobalt mu HSSE kumapangitsa kuti zinthuzi zikhale zoyenera kwambiri pantchito zobowola zovuta kwambiri komwe kulimba komanso kukana kukwiya ndikofunikira.
3. Kabide:
Carbide ndi chinthu chopangidwa ndi chitsulo, chomwe chimapangidwa makamaka ndi tungsten carbide yokhala ndi zomangira zosiyanasiyana. Chimaposa HSS kwambiri pa kuuma kwake, kupirira kutentha, komanso kukana kukwawa. Ngakhale kuti ndi chokwera mtengo kwambiri, zida za carbide zimakhala ndi moyo wautali komanso liwiro lopangira. Zimafunikira zida zapadera kuti ziwongoledwenso.
Kuphimba
Zophimba zobowola zimasiyana kwambiri ndipo zimasankhidwa kutengera momwe zimagwiritsidwira ntchito. Nayi chidule cha zophimba zodziwika bwino:
1. Yopanda utoto (Yowala):
Ndi mtundu wofala kwambiri wa ma HSS drill bits. Ndi wabwino kwambiri pa zinthu zofewa monga aluminiyamu ndi zitsulo zopanda mpweya wambiri, zida zosaphimbidwa ndi zomwe zimakhala zotsika mtengo kwambiri.
2. Chophimba cha Oxide Chakuda:
Amapereka mafuta abwino komanso oteteza kutentha kuposa zida zosaphimbidwa, zomwe zimapangitsa kuti moyo ukhale wautali ndi 50%.
3. Chophimba cha Titanium Nitride (TiN):
Zidutswa zobowola zopangidwa ndi titanium zimagwira ntchito bwino m'njira zambiri chifukwa cha mawonekedwe awo apadera. Choyamba, zimawonjezera kuuma ndi kukana kusweka kudzera mu utoto, zomwe zimathandiza kuti chidutswacho chikhale chakuthwa pamene chikubowola zinthu zolimba, komanso kupereka moyo wautali wautumiki. Zidutswa zimenezi zimachepetsa kukangana ndi kutentha, zimawonjezera luso lodula pamene zikuteteza chidutswacho kuti chisatenthedwe kwambiri. Zidutswa zobowola zopangidwa ndi titanium ndizoyenera kugwiritsidwa ntchito pazinthu zambiri, monga chitsulo chosapanga dzimbiri, aluminiyamu ndi matabwa, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito paukadaulo ndi ntchito zapakhomo. Kuphatikiza apo, zidutswa zimenezi zimalowa m'zinthu mwachangu komanso moyera, zomwe zimapangitsa kuti kudula kukhale koyenera. Ngakhale kuti zobowola zopangidwa ndi titanium zitha kukhala zodula kuposa zobowola wamba, kugwira ntchito kwawo bwino komanso kukhala ndi moyo wautali zimapangitsa kuti zikhale zabwino kwambiri pakugwiritsa ntchito zomwe zimafuna kukana kusweka kwambiri komanso kudula molondola.
4. Chophimba cha Aluminium Titanium Nitride (AlTiN):
Choyamba, zokutira za AlTiN sizimatentha kwambiri, zomwe zimawathandiza kuti azitha kudula ndi kukonza zinthu zotentha kwambiri mwachangu. Kachiwiri, zokutira izi zimathandizira kwambiri kukana kusweka kwa zinthu zouma komanso zimawonjezera moyo wa zida, makamaka pokonza zinthu zolimba monga chitsulo chosapanga dzimbiri, titaniyamu ndi zinthu zopangidwa ndi nickel. Kuphatikiza apo, zokutira za AlTiN zimachepetsa kukangana pakati pa chobowola ndi chogwirira ntchito, zomwe zimapangitsa kuti ntchito yokonza zinthu ikhale yosalala komanso zimathandiza kuti malo odulira azikhala osalala. Zimakhalanso ndi kukana kwa okosijeni komanso kukhazikika kwa mankhwala, zomwe zimathandiza kuti zigwire ntchito bwino m'malo ovuta ogwirira ntchito. Mwambiri, zokutira za AlTiN-coated ndi zabwino kwambiri pakugwiritsa ntchito makina othamanga kwambiri, komanso olondola kwambiri, ndipo ndizoyenera kwambiri kugwiritsa ntchito zinthu zolimba zomwe zimakhala zovuta pakubowola kwachizolowezi.
Mawonekedwe a Jiyometri
1. Utali:
Chiŵerengero cha kutalika ndi m'mimba mwake chimakhudza kulimba. Kusankha chobowolera chokhala ndi kutalika kokwanira kwa chitoliro kuti chichotsedwe ndi kupitirira pang'ono kungapangitse kuti chitolirocho chikhale cholimba komanso kuti chikhale ndi moyo wautali. Kutalika kosakwanira kwa chitoliro kungawononge chitolirocho. Pali miyezo yosiyanasiyana ya kutalika yomwe mungasankhe pamsika. Miyezo yodziwika bwino ndi Jobber, stubby, DIN 340, DIN 338, ndi zina zotero.
2. Ngodya Yobowolera:
Ngodya ya 118° ndi yofala pa zitsulo zofewa monga chitsulo chotsika mpweya ndi aluminiyamu. Nthawi zambiri imakhala yopanda mphamvu yodziyimira payokha, imafuna dzenje loyesera. Ngodya ya 135°, yokhala ndi mawonekedwe ake odziyimira payokha, imachotsa kufunikira kwa dzenje losiyana loyimilira pakati, zomwe zimapulumutsa nthawi yambiri.
Pomaliza, kusankha chobowola chopindika choyenera kumaphatikizapo kulinganiza zofunikira za zinthu zomwe zikubowoledwa, nthawi yomwe mukufuna komanso momwe chobowocho chimagwirira ntchito, komanso zofunikira za polojekiti yanu. Kumvetsetsa mfundo izi kudzatsimikizira kuti mwasankha chobowola chogwira ntchito bwino komanso chogwira ntchito bwino chomwe chikugwirizana ndi zosowa zanu.
